4-Note 3 Chord Groups
Track15 4-Note 3 Chord Groups divides the 7 chords of the C major scale
into 3 lots of very similar sounds.
The Tonic Group contains the I, III and VI chords (C, Em7 & Am7).
In the Sub-Dominant “band” we find the II and IV chords (Dm7 & F).
And the Dominant Group bunches together the V and VII chords (G7 & Bm7(♭5).
This can be very helpful when making harmonic decisions and also
highlights the importance of the bass notes.
